This layer shows the velocity zone also called Coastal High Hazard Area (CHHA). A Coastal High Hazard Area (CHHA) is identified as Zone V or Zone VE on FEMA food maps. These parts of the coastal SFHA are called “V zones” and they show areas where waves and fast-moving water can cause extensive damage during the base food event. In V zones, wave heights are larger than 3 feet. “Zone VE” means that a detailed study has been done for the area, and BFEs have been calculated. The label “Zone V” means that a detailed study has not been done for the area. BFE data is not available, but wave hazards are still expected. Structures in areas mapped as Zone V and Zone VE are subject to stricter building requirements because of the higher risk of damage from strong waves. |
